Hi,
I’m experiencing exactly the same problem. I have noticed that CPU activity increased considerably after resizing my Droplet (to take advantage of the benefits their new plans).

Recently I opened a ticket to follow up on this situation (so far, they have followed my report.. but there has not been a solution).

In fact.. researching a bit, I found this tweet (so I deduce that I’m not the only one who has this reduction in performance): https://twitter.com/Arajdon/status/955104912907689984

My tests:
Just before resizing my Droplet, I took a Snapshot from this one.

As a test, I created a new Droplet from that image in same datacenter -SFO2- (I was assigned a new public IP). Once created, I subjected it to an equal load of intensive to the usual and runs perfectly (it was not perceived excessive CPU load).

Once that I proved that my Snapshot worked well and stably, I decided rebuilt my main Droplet (which presents the problem) expecting it to work fine, but I still have the same problem having an excessive CPU load.

As an additional detail, I have noticed that Droplet’s boot takes too long whitout apparent reason (60 secs aproxly, when it regularly was loading in 15 secs at most).

A very practical solution for me would be to create a new Droplet from my Snapshot. The drawback is that I need to keep my public IP assigned initially.

Thanks!

      Hi,
      Don’t worry. My english is worse (aunque si lo prefieres, mejor en español).

      Well … before changing the size of my droplet (when it still works perfectly), I took a snapshot of this. Once I detected a high CPU usage for no apparent reason, in parallel I created a new Droplet from the snapshot. It worked without problems.

      So… I rebuilt my main droplet from that snaptshot, but it still presents the same problem of high CPU consumption (even when I deactivated the services that could be generating the excessive load).

        Gracias Ivan , cree un ticket a Digital Ocean , veo que desde que Upgrade el droplet me anda muy mal y me llegan alertas de HIGH CPU y MEMORIA ( cuando ahora tengo mas supuestamente).
        Voy a ir actualizando esto a medida que conteste DO.
        @Podias indicarme que servicios desabilitar ? para saber si puedo mejorar un poco el rendimiento?
        Muchas Gracias

          Hola de nuevo,
          En mi caso, deshabilité todos los servicios que instalé en un principio: httpd, postfix, dovecot, mariadb, y spamassassin (aunque antes de redimensionar mi Droplet, todos habilitados representaban una carga aproximada de 30% de CPU).

          De igual manera, hace 3 días levanté un ticket al área de soporte de DO y me recomendaron revisar mis ajustes del sistema para tratar de detectar algún comportamiento inusual, pero no es el caso.

          En mi respuesta inicial, hice referencia a un tuit que me pareció peculiar: https://twitter.com/Arajdon/status/955104912907689984

          También respondí ese hilo y adjunté una imagen del monitoreo de mis recursos a través del panel de administración de DO.

          ¿Por cierto, en qué datacenter tienes tu Droplet?

          ¡Saludos!

          Similarly, 3 days ago I raised a ticket to the DO support area and they recommended me to check my system settings to try to detect some unusual behavior, but that is not the case.

          I also answered that thread and attached an image of the monitoring of my resources through the DO administration panel.

          By the way, in what data center do you have your Droplet?

You should use the top command in your console. It should give you a reading of what processes are using the CPU a lot.

As of April 6th I am also experiencing this (pretty severe) problem in NYC1. My CPU graph looks very similar to Arajdon’s tweet referenced above. I resized with the memory/cpu only option and not disk space. There must be a bug somewhere in the implementation.

Same here, The difference between pre-upgrade and upgrade is obvious. I have upgrades for other companies to do but holding off until this get’s resolved.

I’ve been banging my head against a wall for a couple of weeks now trying to figure out what I’ve broken and how!

It appears I’m having the same issue. I’ve had to go from a $80 droplet to £$60 to handle it…

Has anyone figured out how to fix this? Any word from DO?

Anyone found any solution to this problem? There is no sudden jump in number of users on website. I am upgrading server after every 1-2 months but same problem starts occurring again.

I got this problem too, $5 droplet with 8 wordpress domain. every single day got notification high cpu consumption. Web cannot be access when cpu reach 100% or more. :(

Then, I was create back up all my domain. Destroy and create new one.
Using openlitespeed, php 7, mariaDB and wordpress (install yourself) not using one-click install, now my CPU always below 33% with 9 wordpress domain :)

My guess, when you create droplet and install server automatically, DO provide everything possibility will be use on your server, just maybe :)

So if you familiar with linux server, maybe you can investigation your web server system. But i’m not familiar with linux :)
